Fig 1.
Burch’s membrane opening area and width of gamma zone parapapillary atrophy.
The BM opening is shown as a yellow line and the optic disc margin as a white dotted line. The distance between the BM opening and temporal optic disc margin (red arrow) along the line connecting the fovea and the center of the optic disc (red dotted line) was defined as the width of the temporal PPA without BM (i.e. gamma zone). The blue line delineates the beta zone PPA margin.

A representative case with a different amount of myopic deformation of the optic discs between paired eyes.
Yellow lines in the infrared fundus images indicate BM openings, and white dotted lines delineate the optic disc margins. Red arrows indicate the width of gamma zone PPA along the red dotted lines connecting the fovea and the center of the optic disc. Blue lines delineate the beta zone PPA margins. Humphrey VF data are shown in gray scale and pattern deviation plot.
